Objective To observe the effect of Professor Deng Tietao’s Brain-strengthening Recipe 1 on learning and memory abilities of rats with vascular dementia, and to explore its molecular biology mechanism. Methods The vascular dementia rat model was established by permanent occlusion of the bilateral arteria carotis communis. Sixty male SD rats were randomly divided into 5 groups, namely sham-operation group, model group, nimodipine (5.4 mg·kg-1·d-1) group, and high-and low-dose Chinese medicine groups (57.6 and 14.4 g·kg-1·d-1, respecitvely) . After medication for 30 days, the learning and memory abilities were evaluated by Morris water maze test. The histological changes of the rat hippocampal tissues were observed after HE staining, and the mRNA expression of N-methyl-D-aspartate receptor subunit 2B ( NR2B) in rat hippocampus was measured by real-time fluorescence quantitative polymerase chain reaction (RT-PCR) . Results The water maze test results showed that the escape latency of the rats in the sham-operation group was significantly decreased on the third day, and was significantly decreased in the high-dose Chinese medicine group on the fourth day ( P<0.05 compared with the model group). The results of spatial probe test showed that the times of rats passing through the platform within 60 seconds were significantly higher in high-dose Chinese medicine group ( P<0.01compared with the model group) , but the time for rat staying at the quadrant of the platform in the other four groups did not differ from that in the model group ( P>0.05). HE staining results for the model group were presented as the absence of neural cells in hippocampus CA1 region, karyorrhexis of nerve cells, indistinctness of nuclear membrane, disappearance of nucleolus, shrinkage of nerve cells, increase of cytoplasm acidophily, and reactive hyperplasia of astrocytes. And in the hippocampal CA1 region of high- and low-dose Chinese medicine groups, the injured neural cells were found, and the lesions were slighter than those of the model group. Compared with the model group, the mRNA expression of NR2B was increased in nimodipine group and high-dose Chinese medicine group ( P<0.05) . The mRNA expression of NR2B showed a increasing trend in low-dose Chinese medicine group, but the differences were insignificant compared with that of the model group ( P>0.05). Conclusion Brain-strengthening Recipe 1 has obvious effects on improving the learning and memory abilities of vascular dementia rats, and the therapeutic mechanism is associated with reduction of the degree of neuronal damage in hippocampus and with the upregulation of the mRNA expression of NR2B.

OBJECTIVE:To evaluate the bioequivalence of the domestic pidotimod granules with the imported pidotimod syrup as control.METHODS:20 healthy male volunteers were treated with a single dose(800 mg)of pidotimod granules(test formulation)or pidotimod syrup(reference formulation)by a randomized crossover design,with plasma concentrations of pidotimod determined by HPLC and pharmacokinetic parameters of pidotimod computed,and the bioequivalence between two formulations was evaluated using DAS2.0 program.RESULTS:The pharmacokinetic parameters of the reference formation vs.the test formulation of pidotimod were expressed as follows:t1/2(2.70?0.80)h vs.(2.62?0.84)h;Cmax(4.04?0.59)?g?mL-1 vs.(3.87 ?0.66)?g?mL-1;tmax(2.28?0.44)h vs.(2.13 ?0.43)h;AUC0～14(22.11?4.20)mg?h?L-1 vs.(23.00?4.25)mg?h?L-1;AUC0～∞(22.85?4.42)mg?h?L-1 vs.(23.83?4.52)mg?h?L-1.The relative bioequivalence of the test formulation as against the control was(106.08?22.05)%.CONCLUSION:The pidotimod granules and pidotimod syrup are bioequivalent.

The contribution of particles to cardiovascular mortality and morbidity has been enlightened by epidemiologic and experimental studies. However, adverse biological effects of the particles with different sizes on cardiovascular cells have not been well recognized. In this study, sub-cultured human umbilical vein endothelial cells (HUVECs) were exposed to increasing concentrations of pure quartz particles (DQ) of three sizes (DQPM1, <1 μm; DQPM3-5, 3-5 μm; DQPM5, 5 μm) and carbon black particles of two sizes (CB0.1, <0.1 μm; CB1, <1 μm) for 24 h. Cytotoxicity was estimated by measuring the activity of lactate dehydrogenase (LDH) and cell viability. Nitric oxide (NO) generation and cytokines (TNF-α and IL-1β) releases were analyzed by using NO assay and enzyme-linked immunoabsorbent assay (ELISA), respectively. It was found that both particles induced adverse biological effects on HUVECs in a dose-dependent manner. The size of particle directly influenced the biological activity. For quartz, the smaller particles induced stronger cytotoxicity and higher levels of cytokine responses than those particles of big size. For carbon black particles, CB0.1 was more capable of inducing adverse responses on HUVECs than CB1 only at lower particle concentrations, in contrast to those at higher concentrations. Meanwhile, our data also revealed that quartz particles performed stronger cell damage and produced higher levels of TNF-α than carbon black particles, even if particles size was similar. In conclusion, particle size as well as particle composition should be both considered in assessing vascular endothelial cells injury and inflammation responses induced by particles.

Objective To analyze the clinicopathologic features of primary cutaneous CD30 positive lymphoproliferative disorders. Methods A clinical, pathological and immunohistochemical analysis was carried out in 4 cases of lymphomatoid papulosis and 5 cases of primary cutaneous anaplastic large cell lymphoma. Results Lymphomatoid papulosis was divided into 3 subtypes, A, B and C. The lymphomatoid papulosis of subtype A was pathologically characterized by pleomorphic anaplastic large cells or Steinberg-reed cells scattered or patchly distributed among many inflammatory cells; subtype B showed pathological changes characteristic of granuloma fungoides, and manifested as a broad infiltration zone of lymphocytes in dermis with scattered small- to middle-sized atypical gyrus-like lymphocytes; subtype C was characterized by a diffuse distribution of anaplastic large cells and could clinically subside spontaneously. Primary cutaneous anaplastic large cell lymphoma clinically manifested as subcutaneous nodules or papules, and was pathologically characterized by large, pleomorphic, round or ellipse cells with plentiful, eosinophilic or bicolor cytoplasm, large nuclei and obvious nucleoli. The neoplastic cells characteristically expressed CD30 antigen in both lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma, and all the cases showed a favorable prognosis.Conclusions Primary cutaneous CD30 positive lymphoproliferative disorders are a spectrum of cutaneous T cell lymphoma with favorable prognosis, and a synthetic analysis of clinical, histopathological and immunohistochemical findings is beneficial to the diagnosis of these entities.

Objective To evaluate GGT in combination with B ultrasound for the diagnosis of biliary atresia (BA) infants suffering from obstructive jaundice.Methods A retrospective analysis was made on 69 sick infants including 55 BAs and 14 non-BAs as identified by intraoperative cholangiography.The preoperative laboratory GGT and ultrasound data were collected and analyzed.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy were compared.Results BA patients had significantly higher GGT than Non-BA patients (t =-4.164,P ＜ 0.05).The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of GGT ＞ 306 U/L were 69.1％,92.9％,97.4％,43.3％,73.9％,respectively.In BA group,abnormal gallbladder was significantly associated with proadening portal vein,broadening hepatic artery compared with Non-BA patients (x2 =9.995,P ＜0.05).The accuracy of abnormal gallbladder on ultrasound was 78.3％.When two method combined for the diagnosis of BA,the sensitivity,specificity,positive predictive value,negative predictive value were 92.7％,92.9％,98.1％ and 76.5％ and accuracy can reach 92.8％.Conclusions For obstructive jaundice infants with GGT ＞ 306 U/L and abdominal gallbladder ultrasound finding intraoperative cholangiography should be carried out to make definite diagnosis of BA.
